French LNG containment firm GTT said its unit Elogen has won a contract from Engie’s Storengy for a green hydrogen storage project.
Under the deal, Elogen would provide its membrane electrolyser technology to Storengy, as part of the HyPSTER project, to store green hydrogen produced from renewable energies, according to GTT.
Elogen would design and produce the 1MW proton exchange membrane (PEM) electrolyser and would install its technology in 2022 at the Etrez site, it said.
HyPSTER is a large-scale green hydrogen storage demonstration project, coordinated by storage firm Storengy. Other partners include INERIS, Armines / Polytechnique, INOVYN, ESK, Element Energy but also AXELERA.
The development is the first underground green hydrogen storage project in a saline cavity that received backing from the European Union, the statement said.
Moreover, the Etrez site, France’s leading natural gas storage site in salt caverns in terms of capacity, will rely on local renewable energies such as photovoltaic and hydraulic to produce green hydrogen.
The facility will allow the production of 400 kg of green hydrogen per day.
This production will test the storage of green hydrogen at a level of 2 to 3 tonnes initially until the full capacity of the identified salt cavity is used, i.e. 44 tonnes, the statement said.
Also, experimentation with the storage of hydrogen in a saline cavity and the production of green hydrogen would start in 2023, it said.
